Specification of Lettere Patent.

yTo JZ wharf it may concern:

Beit known that I, ISA/io Simon, a subjectV of the King of Great Britainand'reand, residing at 123Wardour street, London, Eng` land, haveinvented certain newand useful Improvements in Burners for IncandescentGas-Lights or :forl Heating Purposes, of which the following is a.specification'.

This invention relates to improvements in burners for heating orlighting purposes, and when used for the iatter purpose more espe cieilyto those employed for inverted incandescent `ges-iights, such as aredescribed Ain my original application, (of which this is a divisionalpeut) Serial No. 203,042, filed Aprii 13,1904; i

A The invention consists in the special arparts hereinafter described.The invention wiii now be describedwith; :reference to the accompanyingdrawings, in whichf Y Figures 1, 2, 3, and 4 show sectional elevatheinvention into eii'ect. Figs. 5 and 6 show the application of theinvention to an oblique inverted' and to avertical lamp, re actively.Fig. 7 shows its appliceticn to a iowpipe, and Figs. 'S and 9 itsapplication to heating purposes.

In can'ying the invention into Yeil-'eet according to one modication, asshown in Fig. 1, the'upper ende of ,the ,burner or Bunsen tube gisrconeshaped and any suitabe nurnwith ber of openings formed therein bypressing out the cut portions d. Projecting a short distance into thewider end of the cone is a fixed gas-sup lly nozzio f, which alsocarries a circular hood3 or bao r. The hood surrounds and supports theVmixing-cone a, as shown. y' is en Youter -inclosing spherical chamber,toward theiupperend of which a numberof air-inlet orices c are formed.

It will be seen from Fig. fthat the baiiie r is interposed between theYtwo sets of inlet orices c and d and that its iower edge is somedistance beiow them. It therefore follows that air entering at c doesnot directly mix with the geen but is iirst deiected downward into thequiescent ace b; where' it would be heated by the'p nots of combustionim@ pinging upon the exterior'of the chamber ifv e burner were beingusedx in vculmination an inverted' gas-lamp. 1 By ineens of theinjector-like action ofthe gas issuing from-the nozzle j the airisquietly andsteadiiy drawn ci? from the ace b up into the interior of thebaffle rand t ence into the cone either at its open end or three h the'.side openins d. Itwill be understoo that the strengt of the injectoraction wili depend upon the distance the nosziej extends into the mixinc0I 1e. Further, the burning of the lamp wil be unaffected bystrongcrosscurrents of air, since after entering at one sideV they *siii hedeflected round the baie r and out through the openings c et the otherside ofthe spherical chamber, Referrn' to F` 2, a siiniiar constructiento that in Iiig. 1 1s shown, the sha e of the baiiie e in this casebeing spherica with a ynumber of air-inlet openings e formed towerd itslower end. Y 1

Fig. 3 shows a similar arrangement of mixing-cone and nozzle, the shaeef the outer Y incosin chamber being rnodiiied andthe inside bae Ybeingomitted. The outerlohambei* VjY is of approximately heniispherical shapeprovided at its upper end with a number ofeininlet orifices c5 adaptedto register more or less with a simiiar number of oriices in anair-regulator plate k, adjustable Vby means of a projectin pin lc. Thelower edge of the outer cham er is adapted to make Y contact with sradielly-corrugated closingplate l, the corru ations causing a number ofsmall holes l to is formed around its lower end for the purpose ofrelieving any excess pressure Within the chambery'. v The cone is yinthis case carried from a boss which is screwed upon .the fixed`ges-nozzie 4 shows a modified arra ement of' mixmg-eone and gas-nozz1ein w 'ch a decreased velocity is imparted to the ges and air mixture ascompared with the arra ements shown in the previous figures. lr)Ighe-cone a, constructed as already de scrib is anged and secured to theinterior surface of the spherical chamberj toward the .upper end o thelatter in the manner shown, so that the cene expands outwardly and theninwardlyet it supper end, where an opening is left, 1n the center ofwhich the j nozzle f is disposed. To su ply air to the open end of thecone, an auxilio. chamber 'n is mounted above the chamber Lin whichanumber of air-iniet holes c' are formed, a reguator i: being added t9control the amount 'of ithough no baille is shown between the mim -eoneand the inclosing chambery',

such may e used, if desired.

'-In Figs. 3 and 4 an inverted mantle-sup- IOS IIO

port is also shown, the tWo figures showing ront and side elevations,respectively, of the saine form of mantlesupport, while the ulpper partshows different modifications of t ie mixing-conc and gas-nozzle` Themantlering is formed with projections which rest in hooks s, formed onthe ends o the wires m, suspended from the ad justin -sleeve it, whichis secured to the burner-tribe g by a setscrew.

In Fig. 5 the invention is shown as applied to an inverted incandescentgas-lamp arranged to project from a wall or bracket or from a flexiblepipe in an oblique manner. The fittings may be either of the typesbefore described.

Fig. 6 shows an adaptation to an incandescent gas-lamp ofthe usual erecttype. In this case the use of the special mantle-su port above describedis dispensed with, on y the spherical air-chamber with its otherirnmediate fittings being used.

It will be understood that when the burner is not employed for lightingpurposes the mantle attachments are not required and any suitable nozzleor head may be used on the burner-tube g, or the latter alone maysullice.

As shown in F ig. 7, the spherical air-cheniber ma be applied to agas-blowpipe. Gas is sup ied by the iiexible or other pipe u to the spierical air-chamber made in any' of the forms above described. A handleportion o is added, while the mantle and its supports are replaced by a'flame de'lector or spreader iw. No compressed-air pi eis shown. 1t may,however, be led to the 1 aine in any suitab e manner.

Figs. S and 9 show the adaptation to a gas cookmg-stove, the views beingan elevation and plan, res eetively. Beneath a tripod or other snitablgstand a: are disposed one or more heating-burners supplied with gas fromthe common supply-pipe u. The burners are each fitted with a sphericalair and mixing chamber of any of the types above described. The top ofthe stand is fitted with the usual loose cover-plates y, one over eachburner, one plate in Fig. l) being removed to show the burner beneath.

`When ern )loyed forlighting, other forms of mantle-holder may be usedthan those doscribed. I

Any suitable form of by-pass may be used.

Having thus described Iny invention, what l claim as new, and desire tosecure by Letters Patent, is-` 1. A gasburner comlprising a perforatedmixing-cone open at its erger end, a tube extending froln one endthereof, a gas-sup )ly nozzle projecting into its other end, and aperforated casing surrounding the cone substantially as described.

2. A gas-burner com rising a perforatingl mixing-cone open at its ergerend, a tube extending froin one end thereof, a gas-supply nozzleprojecting into its other end, a per- -forated casing surrounding thecone, and a baflie-plate interposed between the perforations 1n theinixingwone and those in the outer surrounding casing, substantially asdescribed.

3. A gas-burner comprising a erforated inixin -cone a open at its largeren a tube exten ing frorn'one end thereof, a gaasupplgy nozzle fprojecting into its other end. a conical hoo or baffle-plate rsurrounding and supporting the mixing-cone, and a perforated sp iericalouter casing, j, substantially as described.

In witness whereof I have hereunto set my hand in the presence of twoWitnesses.
